Engineering perspectives on signal visibility, special indications, intersection operation, and commissioning.
Check the complete signal face, including placement, aiming, background, backplates, indication, and field conditions before choosing a module change. The signal visibility guide explains the system-level review.
A module replacement addresses the visible indication, while detection and controller timing require separate diagnosis. Use the detection and timing review to define the right engineering scope.
The decision may involve signal indications, phasing, controller operation, driver comprehension, and agency approval. See the flashing yellow arrow procurement guide before treating it as a simple lamp substitution.
